TRANSMITTING DEVICE, RECEIVING DEVICE, AND RANDOM ACCESS CONTROL METHOD

摘要

A disclosed transmitting device includes a random access channel generating unit configured to generate a random access channel including a preamble that includes at least a part of control information; and a transmission control unit configured to allocate a continuous frequency band or a discontinuous comb-like frequency band set to a user and to transmit the random access channel in a system that flexibly supports multiple bandwidths.
